Not sure that I qualify as a guru. Can you provide more details as :to in what way Ethernet 'bombed'?

Yes, we installed that poor excuse for a patch and immediately became unable to flip between DOS and UNIX with /etc/suspend and unix restart 1 go.

I'm somewhat more interested in distributed computing applications, and doubling your processing power is always nice. :-) : :Joe> Anybody gots any comments? ;-) : :Hope this helps. It's a good start! ;-) Thanks. : ...
